JSX (JavaScript XML) is a JavaScript extension that allows you to write HTML in the same file as JavaScript code. It is very similar to HTML, but has some key differences, such as the use of className instead of class and self-closing tags (like <img />).

Advantages of JSX:

• Allows for clearer and more compact code writing.
• Integrates easily with JavaScript, facilitating the creation of dynamic elements.
• It is easier to understand and debug compared to string concatenation.

Example of JSX:

              {`import React from "react";
      
              function MyComponent() {
                return (
                  <div>
                    <h1>Hello, World!</h1>
                    <p>This is a JSX example.</p>
                  </div>
                );
              }
      
              export default MyComponent;`}
